Hello, Cataclysm!

If you made a sketch, the answer is obvious . . .

From the equation, , we know all this:Find the equation of the focal chord that cuts the curve at (-4, 2)

. . The parabola opens upward.

. . Its vertex is at the origin.

. . The focus is at (0, 2).

Code:| * | * | * F|(0,2) * (-4,2)*- - - - o - - - -* * | * * | * ------------*------------ |

The focal chord that contains (-4, 2) is the horizonal line: .
